153. Any two of the sequences which I have described as of the Diagonal may be combined, in two ways. First, two sequences of the same mode may be combined. Second, two sequences of different modes, one of the Right Mode and one of the Left Mode, may be combined.
| LD-GB ⍂ 3ds with LD-RO ⍂ 3ds | ||
| Wt | ||
| GB | HLt | RO |
| BV | Lt | OY |
| VR | LLt | YG |
| RO | M | GB |
| OY | HD | BV |
| YG | D | VR |
| GB | LD | RO |
| Blk | ||
In this case we have a combination of two diagonal sequences of the Left Mode in which the colors are taken at the interval of the third. Changing the mode of these two sequences we get them inverted, thus:—
| LD-GB ⍂ LD-RO ⍂ 3ds | ||
| Wt | ||
| GB | HLt | RO |
| YG | Lt | VR |
| OY | LLt | BV |
| RO | M | GB |
| VR | HD | YG |
| BV | D | OY |
| GB | LD | RO |
| Blk | ||
Here the mode is changed and the combined sequences inverted. The combined sequences may be both in the same mode or in different modes. When the modes are different the sequences come into contact, and in some cases cross one another.
| LD-V ⍁ 2ds with LD-V ⍂ 2ds | ||
| Wt | ||
| Y | ||
| OY | YG | |
| O | G | |
| RO | GB | |
| R | B | |
| VR | BV | |
| V | ||
| Blk | ||
In this case we have a combination of two diagonal sequences. One of the sequences is in the Right, the other is in the Left Mode. The colors are in the values of their greatest intensities.

In this case the combined sequences cross one another in the tone of M-RO. The combined sequences have three tones in common. It may happen that the sequences combined will have no tones in common. This is shown in the sequence which follows:—
| LD-O ⍂ 5ths with LD-B ⍁ 5ths | ||
| Wt | ||
| O | HLt | B |
| G | Lt | Y |
| V | LLt | R |
| O | M | B |
| G | HD | Y |
| V | D | R |
| O | LD | B |
